A petrol station in Ireland was trying to increase its sales, so the owner put up a sign reading,

'Free Sex with Fill-Up.'

Soon a local, Paddy, pulled in, filled his tank, and then asked for his free sex.

The owner told him to pick a number from 1 to 10. If he guessed correctly, he would get his free sex.

Paddy then guessed 8, and the proprietor said, 'You were close. The number was 7. Sorry, no sex this time.'

A week later, Paddy comes along with his mate, Barney, and pulled in for a fill-up. Again he asked for his free sex.

The proprietor again gave him the same story, and asked him to guess the correct number.

Paddy guessed 2 this time. Again the proprietor said, 'Sorry, it was 4. You were close, but no free sex this time.'

As they were driving away, Barney said to Paddy, 'I think that game is rigged and he doesn't really give away free sex.'

Paddy replied, 'No, it ain't rigged, Barney. It ain't rigged.....
